Putter type golf club head with improved ball striking face configuration

Abstract

A putter type golf club head having a unique ball striking face configuration to eliminate the dimple effect of grooved putters formed with a series of grooves and intermediate land areas between the grooves extending in a longitudinal direction across the striking face. Each of the grooves is characterized by a plurality of repeating, non-linear wave forms located at the center of the striking face and extending outwardly therefrom.

The invention claimed is: 
     
       1. A putter type golf club head comprising a frontal ball striking face, top surface, bottom leading edge, heel, toe, rear surface and shaft connection; said frontal ball striking face characterized by a plurality of closely spaced grooves formed as repeating, non-linear waveforms; said grooves centrally located on said striking face and extending in a longitudinal direction between said toe and said heel; said frontal ball striking face further includes land areas between said grooves extending in a longitudinal direction across said striking face; said grooves being wider than the land areas separating the grooves. 
     
     
       2. The putter type golf club head of  claim 1  wherein said grooves are further characterized as being undulating in a repeating upwardly and downwardly wave form configuration across said face. 
     
     
       3. The putter type golf club head of  claim 2  wherein each of said grooves is formed with repeating wave form configurations on said putter face and wherein said grooves are arrange in a stack one over another between said top surface and said bottom leading edge of said putter. 
     
     
       4. The club head of  claim 2  wherein said grooves are sinusoidal in shape and alternately disposed upwardly and downwardly across said ball striking face. 
     
     
       5. The putter type golf club head of  claim 1  wherein each of said grooves is characterized by a repeating arcuate configuration across said ball striking face. 
     
     
       6. The club head of  claim 1  wherein each of said grooves is characterized by a repeating trapezoidal configuration across said ball striking face. 
     
     
       7. The club head of  claim 1  wherein each of said grooves is characterized by a repeating chevron configuration across said ball striking face. 
     
     
       8. The club head of  claim 1  wherein each of said grooves is characterized by overlapping an adjacent groove. 
     
     
       9. The club head of  claim 1  wherein each of said grooves is characterized by a discontinuity along the length of the groove. 
     
     
       10. A putter type golf club head having a frontal ball striking face, top surface, bottom leading edge, heel, toe, rear surface and shaft connection comprising:
 a series of individual wavy grooves and land areas separating said grooves extending in a longitudinal direction across said striking face between said toe and said heel; said grooves having a width greater than the width of the land areas between each of said individual grooves; said grooves characterized by a plurality of undulating wave forms in a repeating upwardly and downwardly wave pattern; each wave form of said individual grooves being substantially the same length; said grooves having an upper edge and lower edge; said groove upper edge extending upwardly toward said top surface the same distance as said groove lower edge extends downwardly toward said bottom leading edge; said grooves forming a pattern of repeating waves; said grooves arranged one groove over another between said top surface and said bottom leading edge.
